Medium-pressure columns

Medium-Pressure Columns in Chromatography

Medium-pressure chromatography columns function at pressure ranges typically between low-pressure gravity columns and high-performance liquid chromatography (HPLC) systems. They are widely used for preparative-scale purification where larger sample volumes and faster processing times are required compared to analytical-scale chromatography. Key considerations when selecting a medium-pressure column include column dimension, packing material or stationary phase, particle size, pressure rating, and compatibility with your existing chromatography system.

These columns are commonly employed in:

• Pharmaceutical compound purification and isolation
• Natural product extraction and separation
• Biochemical sample preparation
• Organic synthesis product purification

Specifications often focus on maximal pressure tolerance, column internal diameter, and length, as well as the type of stationary phase (e.g., silica gel, polymer resins). Ensuring the column matches the required flow rates and solvent systems is critical to maintain separation efficiency and equipment longevity.

QuestPair offers listings of medium-pressure chromatography columns that have been refurbished or are second-hand, providing economical options for laboratories upgrading or expanding their purification capabilities.
